>From the comments which have been made, one point that seems to have
been identified is that if this module is first stripped and then
loaded, it can load, but if it's unstripped, it's too big.  This sounds
suboptimal to me - the debug info shouldn't be loaded into the kernel.

However, I guess there's bad interactions with module signing if you
don't do this and the module was signed with the debug info present,
so I don't think there's a good solution for this.
